jsconsole

JSConsole from Remy Sharp is a great way to play with JavaScript in the browser, especially during live coding sessions.

Just like Firebug or the WebKit JavaScript consoles, simply type an expression and JSConsole will evaluate it:

Math.floor(-3.15)
> -4

JSConsole also serves up permalinks for each command: http://jsconsole.com/?Math.floor(-3.15). You can even load external JavaScript libraries with a single command:

:load jquery

Remy has now ported the console to mobile devices using PhoneGap, complete with Websockets support.
